Backflush screen changers introduction:

Continuous backflush screen changer is double piston screen changer with four cavities designed for extrusion lines. Backflush screen changers are working simultaneously without stopping material flowing or mass production for its four filters.

Continuous backflush screen changer design and features:

◆ The design is four channels and four filters. The four filters are working simultaneously without stopping material flowing or mass production. Thus the non-stop screen changing can be achieved.
◆ The exhaust air system is able to fully discharge the air inside the material or perforated plate which is to be replaced. It can avoid air forming in the product during screen changing, thus improve the product quality.
◆ The backflush function can achieve non-stop backflushing filter. The filter can be recycled for more than 200 times.
◆ Four channel design greatly increase filtering area, and meet the higher quality or quantity production demand.
◆ Bigger filtering area is applicable for different material or extrusion products.
◆ The backflush screen changers have better sealing characteristics with rigid sealing. The service life is longer.
◆ It is applicable for high productivity, high efficiency, high quantity and continuous production of large extrusion plant.
◆ It is especially applicable for recycled plastics or large proportion of recycled plastic
◆ With its automatic cleaning filter function, the frequent screen changing can be avoided.
◆ The piston hydraulic screen changer can increase output and save energy consumption.
◆ We can customize various sizes or standards based on the client’s requirement.
◆ It is configured with safety protection cover design.
◆ It has reasonable structure design, easier operation and better working effect.
◆ It is used for chemical fiber, blown film, flat film, cast film, pipe, plate, wire, fiber, granulating, recycling pelletizing, etc.
